Title: Eraser Headtrip
Post by: Bio77 on December 13, 2020, 11:06:42 PM
Finished this up this weekend.  Really fun pedal.

I don't remember the movie too much.  I just remember it was trippy and it has the word head in the title, perfect  ;D

This turns out not to be useful at all once you connect the pedal  ::)

That's some really nice surface-mount soldering.

Outside looks great too- I especially dig your little list on front and those knobs are a neat combination.

Thanks.  I was stoked with the list too, but when I was playing it today it made me laugh because it's completely useless when the pedal's on the floor  ;D

Super clean, super awesome!
Spiffin' decal work including the neato cheat sheet on front, even though you will have to kneel down and get your nose right down to the floor while playing the guitar... cool.

Love it!  Great idea with the graphic and the insides look perfect!

That is a perfect build. Great work!

Yeah, great job on that.

You're thinking of the David Lynch film, _Eraserhead_.  Trippy is downright kind as descriptions of it go.

Very, very nice build!

That's a beauty. That's the first I've seen a pedal like that. So many settings, I bet it's a blast.

What a stellar build.  Clever idea putting the settings chart on the front as well.  I got lazy on this one and used the stock MB graphics.

Solid build! While you probably can't read the chart once plugged up it beats having to remember or pull it up somewhere else. I think I prefer that way rather than trying to put it on the face. One day I will get around to doing it to my arachnid!

Thanks everyone!

If you haven't given this one a try, I think it's worth checking out.  I't one of those pedals that seems to make it's own song parts, if you know what I mean  :P

Excellent! Perfect idea for the artwork and the execution is spectacular. Can't wait to build this one myself, there is no way my FV-1 will be soldered on as cleanly as yours.

Actually reminds me that I need to watch that film one of these days.

That is a great looking build and WAY cooler than the movie ;)

You already had me at David Lynch-themed pedal, but the circuit sounds super-fun to try as well!

This is really great john, inside and out it looks amazing! how are you soldering in smd stuff? I'm only doing smd transistors and jfets  dor the time being and using a chisel tip. I've watched tutorials online and am thinking of getting a hoof shaped tip for my iron. And suggestions for chips cause that fv-1 looks flawless.

Best way I've found to do chips is using solder paste (https://www.amazon.com/Clean-Leaded-Solder-Paste-Grams/dp/B017RSZFQQ/ref=sr_1_5?crid=27K0PG6E18505&dchild=1&keywords=solder+syringe&qid=1608125126&sprefix=solder+syrin%2Caps%2C699&sr=8-5 (https://www.amazon.com/Clean-Leaded-Solder-Paste-Grams/dp/B017RSZFQQ/ref=sr_1_5?crid=27K0PG6E18505&dchild=1&keywords=solder+syringe&qid=1608125126&sprefix=solder+syrin%2Caps%2C699&sr=8-5)) and a cheap heat gun (https://www.amazon.com/Homidic-Handheld-Electric-Portable-Embossing/dp/B07P5WFHJ7/ref=sr_1_3?dchild=1&keywords=heat+gun&qid=1608125162&sr=8-3 (https://www.amazon.com/Homidic-Handheld-Electric-Portable-Embossing/dp/B07P5WFHJ7/ref=sr_1_3?dchild=1&keywords=heat+gun&qid=1608125162&sr=8-3)). 

I've been doing SMD IC's that way for a few years, and it works flawlessly.  Makes a tedious task so much easier!

I use the drag method, I found a youtube video that was pretty good.  You mentioning the hoof tip makes me think you might have watched the same video.  That solder paste Dan mentioned sounds interesting, I'm going to check that out.

I do all the smd first (just one in this case).  First, lay down a liberal coat of flux on the pads with a flux pen.  I use curved tweezers to position the chip.  I put a dab of solder on the tip of my chisel tip.  Once the chip looks positioned, I tack opposite corners to hold it in place.  Then I load up the tip with another drop of solder and drag it across the leads.  If there are any bridges I re-drag across with no solder.  If there is a dry spot, a little more flux and the dab method, like the corners. 

It sounds complicated but it actually goes pretty quick.  When I'm done I clean the PCB with acetone and I'm ready to start populating.  Not sure if it's a trick or not, but I use a 5X diopter magnifying lamp for all my builds, made a big difference for me.
